The pouring mixer (see attached drawing) is a mixing machine fixed
on top of the block mould whose function is to mix the materials
thoroughly before pouring so that they can be made into autoclave
aerated concrete blocks.

The pouring mixer is composed of two units: mixing cylinder and
pouring arm.a) The mixing cylinder is cylindrical in shape. It is made up of
the following components: electric motor, mixing shaft, mixing
blades and diversion tube.b)The pouring arm has a rigid (or flexible) structure. The charging
port of the rigid pouring arm takes the form of two arms and the
charging is controlled by a pneumatic butterfly valve.

4. Operation

a) The pouring mixer works on the principle of diversion-type
mixing. Its mixing is rapid and even. It is driven by a motor,
which rotates in a clockwise direction, driving the mixing shaft
and the mixing blades into rotation. Thus the materials will be
tumbled up and down in the cylinder and the diversion tube. Hence
the purpose of mixing and diversion is achieved.b) The pouring arm is mounted on top of the mould. When the
materials are mixed to the acceptable extent, the butterfly valve
will be opened so that the materials are fed into the pouring arm
and poured into the block mould.

5. Assembly:

a) Put the mixing cylinder levelly on the prepared foundation and
put a rubber pad between the contacting surfaces.b) Fix the pouring arm under the charging port of the mixing
cylinder. The pneumatic butterfly valve should be assembled in
between. The pouring direction, which is determined by the
technological requirement, should be adjusted on site.

6. Trial running and adjustment

a)The following parts should be adjusted after assembly is
completed.i. The rubber belt of the motor should be stretched tight.ii.The gland cover of the mixing shaft should be tightened so that
a perfect sealing of the plastics is formed.iii.The pouring arm should be arranged according to the
technological requirement. The pouring port should be adjusted.b) Trial runningi. The motor should rotate normally in the clockwise direction.ii. The mixing cylinder should work stably.iii. The mixing shaft should rotate freely without jamming or
abnormal noise.iv. The pneumatic butterfly valve should be very sensible in
opening and closing.v.Adjust a suitable distance between the diversion tube and the
underside of the pouring mixer (the common distance is between
12cm～18cm ).

7. Maintenance

a) Daily care:The mixing cylinder, mixing shaft and pouring arm should be cleaned
once a week. Before cleaning, the gland cover of the mixing shaft
should be tightened so that a perfect sealing of the plastics is
formed. All the bearings should be filled up and should be
re-filled every six months.b) Maintenance:The pouring port, the pneumatic butterfly valve and the seals of
the pipelines should be taken down and cleaned once a month.
Packing of the mixing shaft and worn parts should be replaced.

8. Safety:

a) Do not allow anybody to stand on top of the mixing cylinder and
in the vicinity of the pouring arm in the process of pouring.b) Remove all splattered materials completely at the end of each
shift.

Changzhou Mingjie building Material Equipment Manufacturing
Co.,LTd, located in zhonglou development zone in Changzhou, had
been established for more than 30 years and also exported the AAC
block / panel production line over ten years.

1. The International standardization professional plant

The company covers an area of about 48,000 square meters, a total
of five international standardization professional workshops,
respectively, for the storage of raw materials, cutting of sheet
metal, finish machining of parts, assembly of equipment, and
classification and maintenance of finished products, easy to do
quality detection in accordance with the international rules and
regulations by the quality department.

2. Advanced production and inspection equipments

The company has strong technical force, has invested more than 100
million to purchase and improve the production and testing
equipment. So far, the company has more than 30 sets of precision
grade CNC lathes and CNC milling machines with the machining
accuracy of ±1 to 1.5μm. In order to meet the demand of large and
medium-sized workpieces’ manufacturing, the company purchased
three sets of large gantry CNC milling machines with accuracy up to
±2μm. At the same time, in order to meet the needs of special
processing as well as accuracy inspection, the company is also
equipped with five sets of CNC plasma arc and flame double-purposed
cutting machine, three sets of CNC laser cutting machines, more
than ten sets of CNC presses, CNC plate shearing machines, CNC
bending machines, and more than ten sets of high-precision CNC
multi-coordinate measuring instruments.

3. Complete quality control system

To meet the consumers’ needs, as well as the needs for product
quality control and brand building, the company executives develop
the clear quality policy and objectives, and set up a laboratory
dedicated to quality testing. The company invests a total amount of
500million for infrastructure and equipment procurement of the
quality testing laboratory , which building area is over 300 square
meters, also equipped with more than 10 sets of imported testing
equipments..
